Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a tube high in close contactness by shortening a manufacturing process. SOLUTION: On a flat plate which becomes the stock of the tube, recessed parts 2 are provided near both end faces (joined surface obtained when forming a cylindrical body by rounding the flat plate) in the longitudinal direction. These recessed parts 2 extend almost in parallel to the end face of the flat plate, and become hollow in the plate thickness direction of the flat plate. Also, on both end faces of the flat plate, as a means for clinch coupling, a recessed part is formed on one end face, and on the other end face, a projecting part is formed.  When forming the cylindrical body by bending with a coupling jig a work (flat plate stock) 5 on which recessed parts 2, recessed part and projecting part have been formed, the recessed parts 2 of the work 5 are strongly pressed between projections 8a, 9a provided on the punches 8, 9 of the coupling jig and recesses 11a provided on a mandrel 11, and are deformed. Consequently, the close contactness of both end faces of the work 5 is improved.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To extract reliable watermark copy from an image whose quality is considerably deteriorated by using a watermark system where sequence for image and audio signals or the like is decomposed and a unique identifier is imbeded in a perceptively important component of each decomposed part. SOLUTION: Image data X(i, j) being digital form data or data of other form such as photographic data or image data subject to electronic processing by the known method in advance receive frequency conversion 30 such as Fourier transformation.

This mask emphasizes a major area in a frequency spectrum supporting watermark without excess effect on perceptive fidelity. A watermark signal W(k) is inserted to a frequency spectrum component of the converted image data 32. The frequency spectrum image data including the watermark signal receive inverse frequency conversion 34 and image data subject to watermark processing are obtained.
